Wings, air, ground.

The ground effect in flying vehicles is sometimes callled "wing in ground effect". Simply put, for most winged vehicles the closer they fly to a surface, the greater lift they can achieve. The surface in question can be the ground (hence the name) or even the ocean. In fact
the ocean is often thought to be a better option due to the relative lack of obstructions
(buildings, mountains). Some of the first large-scale attempts to make WIG craft, were the Russian "Ekranoplan" military transport projects. Including probably the most well-known (now,anyway) WIG craft to date, the "Caspian Monster". So named by US military intelligence, due to repeated sightings of bizarre short-winged seaplanes, primarliy operating out of the Caspian Sea. WIG craft have not ben used too much to date in actual aplications. They are mostly now recreational and resaerch craft, although various US and world civil/military plane contractors have proposed variations on the Ekranoplan-style large military transport over the years. At present it doens't seem as if any WIG craft will enter wide use any time soon.
